Xanthine sensor development based on ZnO–CNT, ZnO–CB, ZnO–GO and ZnO nanoparticles: an electrochemical approach

New Journal of Chemistry, 2017
The wet-chemical method was used to prepare the various ZnO–CNT, ZnO–CB, ZnO–GO nanocomposites, and ZnO nanoparticles in higher pH medium, which were finally utilized with 5% nafion to produce a thin film of NCs/Nafion/GCE sensor that has a faster response towards selected xanthine with higher sensitivity, lower detection limit, and large linear ...

Solar paint of ZnO/CdS and ZnO/CdSe based on commercial ZnO

Functional Materials Letters, 2016
We report a facile and cheap route to the fabrication of ZnO/CdS and ZnO/CdSe based on commercial ZnO particles. The obtained product can be directly brush printed as solar paint. The results show that the solar cell based on the mixture of ZnO/CdS and ZnO/CdSe have a better light absorption and electron transport ability, and a high power conversion ...

Adsorption of ZnO, (ZnO)2 and (ZnO)3 on MgO(001)

Surface Science, 2008
Abstract We have investigated the adsorption of ZnO, atomic Zn, atomic O and (ZnO) n on the flat MgO(0 0 1) surface by means of density functional calculations. A single ZnO molecule prefers to bind in a position parallel to the surface with the zinc atom above a surface oxygen atom and the oxygen above a magnesium atom.

A novel ZnO nanostructure: rhombus-shaped ZnO nanorod array

Chemical Communications, 2010
A facile scalable two-step approach based on a low-temperature aqueous electrodeposition and a solid-state crystal phase transformation process was developed to grow rhombus-shaped ZnO nanorod arrays which showed markedly improved hydrogen storage capacity.

Electroluminescence from ZnO nanowires with a p-ZnO film/n-ZnO nanowire homojunction

Applied Physics B, 2008
ZnO homojunction light-emitting diodes based on ZnO nanowires were fabricated on Si(100) substrates. An N–In codoped p-type ZnO film grown by ultrasonic spray pyrolysis and an unintentionally doped n-type ZnO nanowire quasi-array grown by an easy low-temperature hydrothermal method were employed to form the homojunction diode.

Manipulation on ZnO heterostructures: from binary ZnO–Ag to ternary ZnO–Ag–polypyrrole

CrystEngComm, 2014
A ternary composite ZnO–Ag–polypyrrole was synthesized through a fast reaction between zinc acetate and hexamethylenetetramine followed by an in situ surface polymerization process. The sample exhibited a superior catalytic performance in the degradation of methylene blue under both UV irradiation and visible light.

Nanaostructured ZnO, ZnO-TiO2 And ZnO-Nb2O5 As Solid State Humidity Sensor

Advanced Materials Letters, 2012
Present paper deals with a comparative performance of n-type ZnO, ZnO-TiO2 and ZnO-Nb2O5 nanomaterials as humidity sensors. ZnO was synthesized through hydroxide route. TiO2 and then Nb2O5 were used as additives for improvement of sensitivity. Scanning electron micrograph of ZnO shows rod-like particles with average diameter 40 nm.
